Biodeisel Fuel Is Produced from Oils Synthesized by and Harvested

Multiple Choice

Biodeisel fuel is produced from oils synthesized by and harvested from living plants. How does the use of biodeisel fuel compare to the use of fossil fuels with respect to the amount of carbon dioxide released to the atmosphere?

A) There is no difference; the combustion of the fuel produces carbon dioxide regardless of its source.
B) It is beneficial; converting plant material to biodeisel permanently traps carbon dioxide and prevents its entry to the atmosphere.
C) It is detrimental; because biodeisel produces lower mileage, more must be burned, causing a proportional increase in carbon dioxide release.
D) It is beneficial; because living plants are the source of the biodeisel, burning it simply represents nutrient recycling.
